Coupled with Thursday's day off, it will give Moreland two days of rest. Washington said Moreland will be back in the lineup Friday against the Mariners.

Moreland has been one of the majors' hottest hitters since late May. He's batting .352 with a .694 slugging percentage, 1.088 OPS, eight home runs, 11 doubles and 20 RBI in his last 29 games.

Eaton began his rehab assignment Monday and hasn't played in 2013 due to the injury. He was expected to be back by mid-June, but this setback could throw a wrench into those plans.

Masste had shoulder surgery in September and suffered a setback prior to the season. He still hasn't thrown off a mound and the club has not made any announcements about a rehab assignment or a return date.

Utley is expected to miss Wednesday's game as a result of the injury, the same one that forced him out of Tuesday's lineup. He said he felt pain and a burning sensation during batting practice. His timetable will become clear following the MRI.

The Cardinals initially thought a nerve condition in Carpenter's shoulder would cause him to miss the season. Progress in a throwing program allowed Carpenter to speculate on returning in the bullpen. Now, with Jaime Garcia out for the year following shoulder surgery, Carpenter is going to try and join the rotation.

The club has stated nothing is a sure thing, but Carpenter's status is a far sight better now than it was in February, when all bets were on his retirement.

Plouffe is expected to get a few days off before taking a concussion test. 

"He took a good shot in the head. That's what this rule is for, to protect the player," manager Ron Gardenhire said. "Give him a little bit of a break here and do what's right. He was a little woozy and that's why there was concern."

Garcia first suffered the shoulder problem May 17 against Milwaukee. He is expected to miss the remainder of the season. Tyler Lyons will take his spot in the rotation for now, but expect that to be in flux with Jake Westbrook's return on the horizon.

Lowrie is considered day to day after X-rays came back negative Tuesday.
